Is RP63263 included in kitchen faucet package

Hi, today I bought 19978-SSSD-DST delta kitchen faucet from home depot. The manual shows a RP63263 3/8 to 1/2 compression adapter kit. Are these suppose to be included as part of the retail package? I'm unable to install the faucet due to my water pipes having 1/2in openings.

Asked by: Anthony Le

Thank you for your question. Delta Faucet model 19978-SSSD-DST does not include the adapters. However, you can order them from your local retailer or wholesaler with model # RP63263.

I bought the 19912-DST faucet and need to connect the 3/8" hoses to a 1/2" pipe. Will Adapters #RP63263) enable me to connect to the water supply?

I live in Argentina and we have 1/2'' pipes. In the adapters description, it says that they adapt to " 1/2-20 UN & 1/2-14NPSM" which I do not know it is the same that 1/2 inch. Thank you!

I have a ½" plastic shut off valve under my sink.  The old faucet line had a ½ Plastic compression fitting.  My new delta faucet has a ⅜" metal compression fitting.  How can I make it work without a new ⅜" shut off valve

Asked by: Dave

Thank you for your question, Dave! The RP63263 adapter converts the 3/8" compression thread on a Delta faucet Pex fitting to either 1/2" compression or 1/2" IPS thread. Although the nut on the PEX line is metal, our fittings are not metallic. Best regards, Edward

Hi, according to your specifications, these convert from 3/8"-24 UNEF to 1/2"-20 UN and 1/2"-14 NPSM. However, according to the UNEF chart, there is no such thing as a 3/8"-24 UNEF. Do you mean the 9/16"-24 UNEF?

Asked by: Yoon

Thank you for your question, Yoon! I apologize for any confusion and would be happy to clarify. UNEF is a thread standard and the threading on this part follows this standard. The nominal diameter of the part may be different than the chart you are referencing but this would not have an affect on the threading itself. Best regards, Edward

I have pet plumbing and my faucet has very low water pressure. We’ve changed the cartridges with no resolution. Could this help?

Asked by: Linda

Hi Linda, Thank you for your question about the Delta Faucet RP63263. This adapter set is used if the supply lines don't fit the home's supply valves. To troubleshoot reduced water pressure, we recommend flushing the faucet with the aerator or spray head removed. Or, some debris and/or foreign material in the lines may be too large to pass through the faucet. To remove this type of debris: 1. Turn off water supply to both hot and cold. 2. Remove all internal components. 3. Turn water supplies back on and let run for 30-60 seconds. (For kitchen and lavatory faucets turn a bucket or similar large container upside down over faucet to deflect the water into the sink.) 4. Turn water supplies off again. 5. Reassemble faucet. 6. Turn water supplies back on. Please reach out for further assistance or with any additional questions! Best Regards, Bryan Digital Communications Specialist
